Abstract (en)
[origin: WO2011079780A1] A memory device includes a first memory array, a first read port, a second read port, and a control input port. The first memory array contains a plurality of memory cells arranged in an array configuration. The first read port is configured to read first data from a single memory cell during a single read cycle, and the second read port is configured to read second data from a group of memory cells controlled by a common word line. Further, the control input is configured to receive a mode signal indicating a functional mode for the memory device including a first read mode and a second read mode. When the mode signal indicates the first read mode, the first read port is used to read the first data. When the mode signal indicates the second read mode, the first read port is used to read out the first data and the second read port is used to read the second data.
